I have created a site mesh which is clearly visible in the 2D view, however when i switch to a 3D view the screen is blank. However I can select the mesh and the corners and the other nodes appear as dots, but that is all I can see. If I hit esc then everything is blank again. I have all layers turned on, and everything is as I always have it. I have attached a screenshot to illustrate, the blue lines are the perimeter shape (at 0), while the black dots above are where the surface of the mesh should be.
Any suggestions appreciated.
